Definitions
- the invention relates to a method and an apparatus for manufacturing active ingredient dispersions.
- active ingredient-based dispersions are required are produced, e.g. B. in the paint and pharmaceutical industries. Often it is not possible the active ingredient, e.g. B. the dye or the pharmaceutical ingredient, directly in one disperse aqueous liquid. In particular, the active ingredient particles are then not in the desired micronized form.
- European patent EP 0 322 687 proposes a method for producing a pharmaceutical form which comprises an active ingredient and a carrier.
- This is a fluid gas, an active ingredient and carrier materials, which can also be dissolved in a liquid, into a spray tower introduced so that the fluid gas absorbs the active ingredient and carrier.
- a separator then separate the fluid gas from the resulting active substance / carrier combination, see above that this can be removed from the separator.
- this procedure produces dry drug particles, but not liquid dispersions.
- Fluid gas is understood to be a substance present at atmospheric pressure as a gas or vapor, which is compressed to near its critical point or beyond and therefore as under or supercritical fluid is present.
- the object of the invention is to provide a method and an apparatus for Production of active ingredient-containing dispersions which result in a particularly fine distribution of the Lead active ingredient in the dispersion.
- the micronized active ingredients should not agglomerate.
- the object is achieved by a method in which an active ingredient is in a fluid gas is dissolved and the drug-laden fluid gas in a saturated with this gas Liquid is dispersed, so that there is a first dispersion of liquid and drug-laden fluid gas.
- the active ingredient is made molecular by diffusion transferred the gas to the phase boundary.
- the solid then only forms on the Phase boundary and gets from there directly into the liquid, where it immediately, preferably is stabilized by protective colloids so that agglomeration is excluded.
- This the first dispersion is formed with a second dispersion of active ingredient Liquid and fluid gas passed through a dwell.
- the second dispersion is then separated into a gas phase by phase separation without prior relaxation a third dispersion of liquid and active ingredient separated. Part of the third dispersion is finally reused to form the first dispersion with the fluid gas. It is advantageous that a large part of the gas without recompression to dissolve the Active ingredient can be reused.
- the active ingredient used preferably consists of a mixture of several active ingredients.
- Preferred active ingredients are dyes, vitamins, carotenoids, polymers, liposomes, pharmaceutical active ingredients or crop protection active ingredients.
- Preferred fluid gases are CO 2 , N 2 O, ethylene, propane, H 2 O, NH 3 , hydrocarbons, alcohols and mixtures of these substances.
- Water or an organic solvent is preferably used as the liquid, which is preferably enriched with additives from protective colloids such as surfactants, polymers, celluloses, dextrins or proteins such as gelatin and / or emulsifiers or the like.
- a device includes an extractor for the Dissolution of an active substance in a fluid gas, which is connected via a line to a Mixing device for dissolving the fluid gas loaded with active substance in a liquid connected is. The liquid is fed to the mixing element via a further line.
- the device also contains a dwell time with a separator is connected in which the gas is separated from the liquid containing the active ingredient.
- the separator has discharge lines for the separated gas and for the separated liquid on.
- the device contains a return for a part of the separated Liquid to the mixing element.
- the discharge for the separated gas carries it out the separator back to the extractor.
- the fluid gas also becomes the extractor 4 supplied with the active ingredient 5 and achieves that as an active substance-laden fluid gas Mixing device 7.
- the mixing device and the subsequent dwell time 8 takes place however not a solution of the fluid gas in the liquid, but a dispersion of the active substance-laden fluid gas with a liquid supplied via line 12, which with is saturated with the same gas.
- the active ingredient dissolved in the fluid gas arrives by diffusion the phase boundary precipitates in the form of microparticles and is then in the liquid, preferably by protective colloids.
- the resulting second dispersion from Liquid and fluid gas loaded with active substance is not relaxed, but directly to you Separator 11 supplied. Via discharge line 15, which is provided with an expansion valve 21 part of the liquid loaded with the active substance is removed.
- This solution is in the separator 22 separated from the dissolved gas and withdrawn via line 23.
- the gas is over Line 24 is returned to the compressor 2.
- the other part of the drug-laden Liquid is withdrawn from the separator via line 16, through line 18 and compressor 19 with fresh liquid and supplemented by the circulation pump 13, the Compensates for pressure loss in the pipes, promoted in a circle.
- the liquid is then over Line 12 fed back to the mixing element 7.
- the separated fluid gas is over Line 14, circulation pump 17 and line 20 returned to the extractor 4.
